Upgrade deployment image to k8s 1.27
Context
Triage-ops GKE cluster is at version 1.27.
There needs to be a maximum of one minor version between kubectl
and the cluster version (we're good so far, but won't be as soon as the cluster upgrades to 1.28).
What does this MR do and why?
Upgrades kubectl
to version 1.27 for triage-ops deployments.
